Linux Kernel upgrade centos

Upgrading the Linux kernel to centos is not a negative term! For example, for linux ~ The virtual machine is installed with CentOS 5.5 and the kernel is 2.6.18.

Upgrading the Linux kernel to centos is not a negative term! For example, for linux ~ The virtual machine is installed with centos 5.5 and the kernel is 2.6.18. I want to upgrade my kernel while I am busy with the call of the party that keeps pace with the times! So du Niang had a while, but things were always unable to follow the expected trajectory, but life had to continue. feel for yourself! I chose to upgrade www.2cto.com to 2.6.19. 1. download 2.6.19's internal linux-2.6.19.tar.bz2 on the ftp://ftp.kernel.org/pub/linux/kernel/v2.6, cp linux-2.6.19.tar.bz2/usr/src/kernel/cp to/usr/src/kernel (some release versions do not have the kernel directory) 3. extract the tar-jxvf linux-2.6.19.tar.bz2 to the current directory
4. configure the kernel. I suggest there are two methods a, make menuconfig directly, then quit, save B, put/boot/config-2.6.18 directly cp to the root directory. config 5, make 6, make bzImage 7, make modules 8, make modules_install 9, mkinitrd/boot/initrd-2.6.19 2.6.19 10, cp/usr/src/kernel/linux-2.6.19/arch/i386/ boot/bzImage/boot/vmlinuz-2.6.19 www.2cto.com 11, vim/boot/grub. conf # grub. conf generated by anaconda # Note that you do not have to rerun grub after making changes to t His file # NOTICE: You have a/boot partition. this means that # all kernel and initrd paths are relative to/boot/, eg. # root (hd0, 0) # kernel/vmlinuz-version ro root =/dev/VolGroup00/LogVol00 # initrd/initrd-version.img # boot =/dev/hdadefault = 1 timeout = 15 splashimage = (hd0, 0) /grub/splash.xpm.gz hiddenmenu www.2cto.com title CentOS (2.6.18-194. el5) root (hd0, 0) kernel/vmlinuz-2.6.18-194.el5 ro root =/dev/Vo LGroup00/LogVol00 rhgb quietinitrd/initrd-2.6.18-194.el5.img add your own startup item and kernel title CentOS (2.6.19-lin) root (hd0, 0) kernel/vmlinuz-2.6.19 ro root =/dev/VolGroup00/LogVol00 rhgb quietinitrd/initrd-2.6.19.img OK, done, reboot on it!
